To @ZZ whom it may concern,.-

Be it known that I, LEWIS M. COOK,a citizen ot' the United States,residing at Neenah, in the county ofl/Vinnebago and State ofWisconsin,have invented a new and useful Im# provement in Snap-Hooks, ofwhich the following is a specification. Y

My invention relates to an improvement in snap-hooks for general useupon different parts oil harnesses, and upon ropes, chains, and allplaces for which the use of snap-hooks are adapted; and the object of myimprovement is to adapt the hook for engagement and disengagement withease and without requiring the use of the individual ngers of the personusing it, the snap-hook only requiring to be grasped in the hand and aforcible movement of the snap-hook made lengthwise of it and toward orfrom the part to be connected with it, whereby the improvement isparticularly adapted for use in the dark or when the hand of the personusing it is encurnbered with a glove or mitten. I attain these objectsby means of the construction of the snap-hook which is shown in theaccompanying drawings, in which- Figure l is a top view ot the snap-hookwith the end broken. Fig. 2 is a side elevation thereof, the hook beingcomplete. Fig. 3 is a side elevation, the central portion of the body ofthe snapdioolr being in section vertically upon the line o. a of Fig. l;and Fig. el is a like view of said central portion, showing amodification in its construction.

Similar figures of reference indicate like parts in the several views.

l indicates the body ot the snap-hook; 2, a loop for its connection witha strap or other part with which it may be desired to permanently attachit g 3, a loop at the opposite or hook end for the temporary connectionwith it of a ring, harness-bit, or other like part; ei, a slot which isformed in the body of the hook; 5, a three-armed spider which is pivotedfor revolution within the slot; 6, a spring arranged within the slot;6', a pin for holding said spring in position therein; 7, a removablepiece for covering the opening to the slot upon the back or lower sideof the snap-hook in Fig. 3; S 8', screw-holes in which screws may beinserted for connecting the piece 7 and spring 6 to the body of thehook.

shown in Fig. 3 is used, may be cast of a suitv able metal and tittedtogether, the spring being bent ot the proper form for its suitableaction upon the arms ofthe spider 5. In Fig. 3 the spring is providedwith a hole corre spending in position with the hole S or 8', throughwhich a screw may be inserted for holding the spring securely, the samescrew also serving to secure one end ot the piece 7 to the body of thehook. The modication, Fig. a, being used, the spring is held within thepocket by means of a pin 6. the bottom of the slot and thereby forming apocket, and locating the pocket directly under the end ot the hook l',it is more difcnlt for foreign substances to enter and clog the springand spider than it would be it the slots were open and exposed on bothsid es, as where they are located in the shank instead of the body ot'the device.

The spider is arranged for revolution within the slot upon the pivot 5with two ot' its arms (excepting when a connection or disconnection isbeing made) arranged to bear upon the tree end of the spring, wherebythe third arm ot the spider willextend upward and obstruct the passagebetween the body or swell of the hook which is around the spider and theend l ot the hook. As one of the arms ot' the yspider will always extendupward toward the end l', (excepting when the spider is being turnedaround upon its pivot for the entrance to the loop of some article orfor its removal therefrom,) nothing can enter or leave said loop withoutthe application of sufficient force to said arm to revolve the spiderone notch-i'. e., until thisarm is turned down against the spring andanother one takes its place. By making the spider with three similararms and locating them equidistant from each other, as above described,it is free to rotate in either direction, and it is not necessary toinsert it in any particular manner, as must be done with a two-armedspider, and after it has been inserted, as many attachments can be madewith the one hook, as desired, by simply rotating the spider until allof the attachments have been made, as where it is desired to place twoor more rings in the hook, and the attachments can be diseon By closingvIOO Vnected by simpiyzrotating the spider in the opposite direction,Which could not be doneV witha two-armed spider which oscillates uponits pivot instead of rotates;

By'providing a spring of the properk stitt ness the hook can beadaptedfor heavy or riight uses,` whereby a slight pull orpnsh upon f the hookwill connect or disconnect the same from the ring or other article yWithwhich it ,and the siot around it from the entrance of snow, ice,dirtyffrc.,y and thereby providing for the free and easy working ofthespider and f spring.

Having described my yini'Tentioini what j claim,A and desire to secureby Letters Patent,

l. A snap hook, the upper ySurface of the bodyo which is provided with apocket, and

, the hook portion extends up over and formsr a cover for the same, aspring Within the pocket', and a spider pivotally secured Within thepocket above thespring, saidspider having'tnree similar armsequi-distant 'from each other and of the same length, two of said armebeingadapted to bear against thespring and the remaining one projectsabove the upper isurface of the ,body adjaeentto the hook, substantiallyas set forth; t

7 2'. A snap lioolgthe body ot' which is provided With a slot andthehook portion extends up over the slot and forms a cover for the same,a removable piece over the pocket f upon the opposite side of ,thetbody, aspiring r yWithin the slot, one end of which is located Yrbetween the body and one end of the removalolek piece, anda threearrnedspider pivotally; secured Within the slot abovethe rfree end of the,spring, said arms being equidistant `from eachotherand of thesamielength,two arms of which are adapted to rest against the spring andtheother arm is adapted to project beryond the surface of the body adjacentthe hook, substantially as set forth.y f f LEWIS M.
